The Origin of Quorum Systems
نویسنده
چکیده
A quorum system is a collection of subsets of nodes, called quorums, with the property that each pair of quorums have a non-empty intersection. Quorum systems are the key mathematical abstraction for ensuring consistency in fault-tolerant and highly available distributed computing. This paper is a brief overview of the evolution of quorum systems, with emphasis on their role in two fundamental applications: distributed storage and replication.

Quorum Sensing in Microbial Virulence
Cell-to cell communication occurs via a signaling pathway referred to as quorum sensing. There are four main types of these systems according to the chemical nature of signal molecules used by microorganisms to elicit expression of target genes in response to environmental stimuli or need of microbial communities. Type I system acts by using acyl homoserine lactones as signals to trigger the ex...

Abstract Introduction: Bacteria communicate with each other by using molecular chemical signal, which are called autoinducer. By the increase of concentration of these signals, which is the result of increase cellular density, they coordinate gene expression in a microbial community. This process is called Quorum sensing. Considering the importance of urine tract infections prominent role of Qu...
متن کاملQuorum quenching for the management of dental plaque microbes
In the present study, variation among different bacterial strains was observed in the plaques of tobacco chewers (TC) as compared to those from normal persons (non tobacco chewers) (NTC). Bacterial strain J1 (dominant in the plaques of NTC) did not initiate the process of adhesion (biofilm formation) until it appeared to have reached a required population density necessary for the production of...

Objective(s): Honey’s ability to kill microorganisms and even eradication of chronic infections with drug-resistant pathogens has been documented by numerous studies. The present study is focused on the action of honey in its sub-inhibitory levels to impact on the pathogens coordinated behaviors rather than killing them. Materials and Methods:</strong...
متن کاملThe Role of Intrinsic Noise in Origin of Quorum Sensing
Many biological phenomena about quorum sensing in bacteria are driven by experimentally and mathematically in the last few decades. Symbiosis, virulence etc. are the major area in which these theoretical models work well. But no specific origin was established so far which can explain quorum sensing itself. This weakly nonlocal fluid dynamical model of bacterial communication system introduces ...
